How to remove interceptors?

Hi all,

As suggested by book/documentation I'm using adviceWith method to add interceptors to my existing routes, like this:

                for (int i = 0; i < camelContext.getRouteDefinitions().size(); i++) {
                               camelContext.getRouteDefinitions().get(i).adviceWith(camelContext, new RouteBuilder() {
                                               public void configure() throws Exception {
                                                               intercept().process(customCamelAuditorProcessor);
                                               }
                               });
                }

Question is, would it be possible to remove/disable the added interceptors?

Thanks in advance,
BR,
Marcos.

Hi,

There are 2 ways to do this.

a> Static: You do not get rid of the interceptor (i.e the interceptor does
get invoked but you eject immediately if a header value (boolean) is set in
the payload. This will allow you to switch the interceptor code on/off on
demand.

b> Dynamic: You stop to the route, modify the route and re-load the route
without the interceptor. The camel context has API's to add/modify/remove
routes in a running camel context. The side-effect of this is that the route
is unavailable for a small period of time. 

Hope this helps.

Cheers,

Ashwin...

You can use intercept().when(predicate).process(processor) and have
predicate depend on a settable value.
